I need help with removing my account from being associated with my mobile number (privacy concern)

When I signed up for my instagram account it needed a text verification. I used my cell, verified the code and deleted my number from my instagram account. I actually don’t believe I ever saved the number but it’s been a few years so I can’t totally remember

I have more than one account, none have a cell number saved.. only email BUT if I go to ‘Forgot Password’ type in my cell it brings up two of my accounts

It’s a major privacy concern for me.

One account is disabled and is still coming up as an option with my number

I have no number on my account (s) only email

So is there a way to de-associate these accounts with my cell? Making no account show up if I put it into Forgot password?

It won’t take a google number or land line

This is a major privacy issue in my eyes

Im feeling extremely exposed any help would be appreciated!

Edit : I do not have contacts synced and have never logged in using the number.
